Data from: The monophyly of Euparkeriidae (Reptilia: Archosauriformes) and the origins of Archosauria: a revision of Dorosuchus neoetus from the Mid-Triassic of Russia

Roland B. Sookias, Andrey G. Sennikov, David J. Gower & Richard J. Butler
Euparkeria capensis is resolved as the sister taxon to crown Archosauria in many cladistic phylogenies and provides a key outgroup which may approximate the ancestral archosaur morphology. Several other taxa have been referred to the family Euparkeriidae, but the monophyly of this taxon remains doubtful and largely untested. In order to test this monophyly, the archosauriform and putative euparkeriid Dorosuchus neoetus from the Mid-Triassic of Russia is reexamined in light of recent work on the...

Data from: Behaviour-related DRD4 polymorphisms in invasive bird populations

Jakob C. Mueller, Pim Edelaar, Martina Carrete, David Serrano, Jaime Potti, Julio Blas, Niels J. Dingemanse, Bart Kempenaers & Jose Luis Tella
It has been suggested that individual behavioural traits influence the potential to successfully colonize new areas. Identifying the genetic basis of behavioural variation in invasive species thus represents an important step towards understanding the evolutionary potential of the invader. Here, we sequenced a candidate region for neophilic/neophobic and activity behaviour – the complete exon 3 of the DRD4 gene – in 100 Yellow-crowned bishops (Euplectes afer) from two invasive populations in Spain and Portugal. The...

Data from: Taxonomy of the proterosuchid archosauriforms (Diapsida: Archosauromorpha) from the earliest Triassic of South Africa, and implications for the early archosauriform radiation

Martín D. Ezcurra & Richard J. Butler
Proterosuchidae is one of the first clades of Archosauriformes (archosaurs and closely related species) to appear in the fossil record, with the richest sample of the group coming from the Lystrosaurus Assemblage Zone (earliest Triassic) of South Africa. Four nominal proterosuchid species were described from South Africa during the twentieth century (Proterosuchus fergusi, Chasmatosaurus vanhoepeni, Chasmatosaurus alexanderi and Elaphrosuchus rubidgei), but interpretations of their taxonomy have been widely disparate. The most recent taxonomic revision concluded...

Data from: Speed of adaptation and genomic footprints of host-parasite coevolution under arms race and trench warfare dynamics

Aurélien Tellier, Stefany Moreno-Gámez & Wolfgang Stephan
Coevolution between hosts and their parasites is expected to follow a range of possible dynamics, the two extreme cases being called trench warfare (or Red Queen) and arms races. Long-term stable polymorphism at the host and parasite coevolving loci is characteristic of trench warfare, and is expected to promote molecular signatures of balancing selection, while the recurrent allele fixation in arms races should generate selective sweeps. We compare these two scenarios using a finite size...

Data from: Inferior cerebellar hypoplasia resembling a Dandy-Walker-like malformation in purebred Eurasier dogs with familial non-progressive ataxia: a retrospective and prospective clinical cohort study

Filipa Bernardino, Kai Rentmeister, Martin J. Schmidt, Andreas Bruehschwein, Kaspar Matiasek, Lara A. Matiasek, Alexander Lauda, Heinz A. Schoon & Andrea Fischer
Cerebellar malformations can be inherited or caused by insults during cerebellar development. To date, only sporadic cases of cerebellar malformations have been reported in dogs, and the genetic background has remained obscure. Therefore, this study`s objective was to describe the clinical characteristics, imaging features and pedigree data of a familial cerebellar hypoplasia in purebred Eurasier dogs. A uniform cerebellar malformation characterized by consistent absence of the caudal portions of the cerebellar vermis and, to a...
